Description
Buffer overflow in Firebird 1.0.2 and other versions before 1.5, and possibly other products that use the InterBase codebase, allows local users to execute arbitrary code via a long INTERBASE environment variable when calling (1) gds_inet_server, (2) gds_lock_mgr, or (3) gds_drop.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
